Review: Pantech Matrix Pro
The Matrix Pro uses Windows Mobile 6.1, and brings nothing new to the mobile operating system. It has the same Today screen that uses the up-and-down and left-right scrolling through the phone's features (such as left-right scrolling through your varying email accounts from a single "email" line) without pulling up the Start menu.
Aside from the quick access that this home page gives you to your calls, messages, photos and settings, you have to use the Start menu to get at the rest of the applications buried in WinMo.
The Matrix Pro's Start menu doesn't appear to be customizable at all. Rather than offer a list of applications along the left side of the screen, the Start button simply opens the main menu page of the Matrix Pro. This menu is arranged in a grid configuration, and also doesn't appear to be customizable.
